Lubricants and Mold Release

Here are some of the most frequently asked questions with their answers from Lubricants and Mold Release.

I want to improve the wetting properties of my oil based lubricant onto metals. Can I reduce the surface tension?

The addition of silicone surface additive will reduce the surface tension of the oil and improve the wetting onto metals. You should try 0.2% BYK-310 and BYK-333.

I am adding graphite or molybdenum disulfide (moly) into my oil based lubricant. During storage the particles form a settlement at the bottom. What can I do?

Wetting and dispersing additives can help to keep the particles dispersed and suspended and avoid sedimentation. DISPERBYK-2157 and BYK-P 105 are first recommendations to test.

My water based forging lubricant does contain graphite. I want to increase the graphite content but the viscosity is getting too high. Any way to reduce viscosity.

DISPERBYK-2012 and DISERPBYK-2015 will significantly reduce the viscosity of the graphite in water dispersion.

I want to formulate a grease for high temperature application and NSF H1 approval for incidental food contact. Can you offer a suitable thickener system?

CLAYTONE-40 is our first recommendation as thickener for high temperature applications and NSF H1 approval. As an ingredient for lubricants and greases it is NSF HX-1 listed.

I am looking for mold release additives with low residue in the mold.

Wax emulsions based on Polypropylen do show a very low build up and residue in the hot mold after several cycles. AQUACER 3500 and AQUACER 597 are typical PP wax emulsions as release agents for this kind of application.
